Linux Foundation expands open source agentic AI with Solo.io’s Rust-built Agentgateway, a secure gateway designed for interoperability, governance, and the future AI agent mesh.
The Linux Foundation is reinforcing its role as a neutral hub for open source agentic AI by bringing in another key project. Following Google’s donation of the Agent2Agent (A2A) protocol in June and Cisco’s contribution of AGNTCY in July, the Foundation has now welcomed Solo.io’s Agentgateway.
Announced at the Open Source Summit Europe in Amsterdam, Agentgateway was originally launched as Gloo AI Gateway, an open source data plane designed for agent-to-agent and agent-to-tool communication. With a focus on security, observability, and governance, it supports both A2A and the Model Context Protocol (MCP) developed by Anthropic. Contributors already include AWS, Cisco, Huawei, IBM, Microsoft, and Red Hat.
Linux Foundation executive director Jim Zemlin described Agentgateway as a “secure management layer for interactions between AI agents” across diverse frameworks and protocols.
Lin Sun, vice president of Solo.io, highlighted its role in connecting agents and mediating traffic securely:
“In a nutshell, Agent Gateway is serving as the gateway in between your agents, in between your agent and the MCP server, in between your agent and your large language model, to help mediate that traffic to apply security policies such as authentication, authorization, to be able to do governance and control and also provide observability on top of that.”
Built from the ground up in Rust after Solo.io abandoned attempts to adapt Envoy, Agentgateway functions as a unified data plane with integration options for frameworks such as LangGraph, Agents SDK, Claude Desktop, and kagent.
Solo.io, founded in 2017 by CEO Idit Levine, is positioning Agentgateway as a building block toward a mesh of AI agents—an open, scalable architecture for collaborative intelligence, free from vendor lock-in.
